car embodying my invention, the right-hand portion being in horizontalsection and the flooring thereof. removed. Fig. 2 is an end view of acar embodying my invention, the right hand portion being in elevationand the left-hand portion in vertical transverse section. Fig. 3 is alongitudinal central vertical section of the end of a car embodying myinvention, a portion of the lining of the side wall of-the car brokenaway. Fig. 4 is a detached face view of the end sill of the car, thebuffer-caps and buffer-springs being removed to show thefriction-flanges on the interior of the spring-chamber. Fig. 5 is ahorizontal central section of the end sill shown in Fig. 4. Fig. 6 is anenlarged vertical transverse section of the end sill between thebuffers. Fig. 7 is an enlarged central section of one of the buffers,the buffer-spring being in elevation. Figs. 8 and 9 are respectively endand side elevations of the buffer-cap. Fig. 10 is a transverse sectionof one of the flanged plates used in the car construction. Fig. 11 is atransverse section of one of the lining and flooring planks employedwhere a flanged plate is used in the car construction. Fig. 12 is atransverse section of a modified form of plate for use in lieu of theflanged plate.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of metallic cars for thetransportation of merchandise in general, and especially such as ore,coal, 85c, which from their nature, bulk, and weight tend to overloadand deteriorate the structure, and has for its objects to reduce theweight and stiffen the car structure the better to enable it towithstand strains and shocks and toprotect the interior metallic wallsand floor of the car against injury from contact with its contents, aswell as to facilitate the cleaning and repair of the car withoutmaterially reducing the capacity of the car.

To obtain the first and last of the abovenoted results, I construct thecar of flanged or corrugated sheet metal and of planking kerfed orchanneled to receive the flanges or corrugations or flanges andcorrugations of the sheet metal, the latter forming the interior wallsand flooring of the structure, wherebya lighter or thinner sheet ofmetal. may be employed,the apposition or extended contact of the woodlining therewith supporting the same against bending or buckling, aswell as protecting the same from deterioration, and such a constructionembodies the main feature of my invention.

There are other minor features of invention,

all as will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that othersskilled in the art to which it appertains may apply the same.

In the drawings, 1 1 are side sills, 22 inter mediate-sills, and'3 oneof the end sills, of a car, of which the intermediate and side sills maybe I-beamsor other suitable forms of structural iron, while theend-sills 3 are preferably steel castings open on the inner face andreinforced by longitudinal and transverse (or vertical) webs or flanges3 3 on the interior, the latter so disposed as to correspond with thearrangement of the intermediate sills 2 2, to the ends of which (seeFigs. 2 and 3) the webs 3 are bolted, riveted, or otherwise secured.

Cast integral with or, if preferred, attached to the end sill 3 are thespring-pockets 4 of the buffers, preferably of cylindrical form andhaving on their interior spirally-disposed friction-flanges 4 whichengage in similar slots of the buffer 5. (See Figs. 7, 8, and 9.)

5 indicates the louder-cap, of cylindrical shape and cup form, providedwith the spirally-disposed slots 5, which recieve the spirally-disposedfriction-flanges 4, and with a center post or bolt 5*, which passesthrough a hole 4* in the bottom of the spring-pocket, said post or bolthaving an eye 4 for a pin, which confines the cap 5 to the spring-pocketd and the buffer-spring 6 between the cup and pocket, as indicated inFigs. 1 and 7 of the drawings. As a result of the above-specifiedconstruction of buffer or its equivalent the buffer-spring will bedampened or controlled in both compression and expansion by the frictionincident to the spirally-disposed slot and flange, and the car structurewill be relieved of those intense sudden shocks due to the action andreaction of the buffersprings as commonly applied to the end sills.

The metallic floor of the car is composed of either flanged orcorrugated plates 7, (see Figs. and 12,) transversely disposed withrelation to the side sills l 1 and intermediate sills 2 2, the flangesextending upward into the car, and said plates may be connected witheach other by rivets passing through the contacting flanges and with thesills by suitable bolts 'or rivets. Upon said metallic floor comprisedof the flanged or corrugated plates 7 is laid a wooden floor comprisedof planking 8, having in its under surface a series of kerfs or channels8, adapted to receive the ribs or flanges of the flanged or corrugatedflooring-plates 7, and said kerfs or channels are of such depth as tobring the under surface of the planking in extended contact with theupper surface of the plates preference the plates 7 and planking 8 arearranged to break joints, as at as, (see Fig. 3,) and the planking 8, ifdesired, may be secured to the metallic flooring by bolts 8 (see Fig. 1)or in other suitable manner. The side and end walls of the car are ormay be also constructed of like corrugated or flanged plates 9, arrangedwith the flanges turned inward, connected by rivets through the adjacentflanges and braced at intervals by vertically-disposed flanged channelor U bars 10. Of the wall-plates 9 those constituting the side walls arepreferably disposed longitudinally of the car and those constitut-- ingthe end walls transversely of the car, the side and end plates beingunited at the corners by an inner angle-plate l1 and an outer cap-plate12, or in lieu of the latter a caststeel corner-post (see Fig. 1) may beemployed, if desired. The lower plates 9 of the side and end walls ofthe car may be extended down so as to rest upon or contact with thefloorplates 7, but preferably as facilitating repairs the lower flangeof lower plates 9 (see Figs. 2 and 3) rests upon the floor-planking 8.

The interior side and end walls of the car are or may be lined bylongitudinally and transversely disposed planking 13, having in thatface which comes in contact with the wall-plates 9 a series of kerfs orchannels in all respects like that of the flooring 8 and for a likepurposeviz., to receive the flanges and corrugations of the metallicplates of which said side and end walls are comprised, and also, as inthe case of the flooring, the planking of the side and end walls ispreferably arranged to break joints with the plates 9 of said walls.

As a result of the construction hereinbefore described a very stiff andstrong car structure can be obtained by combining comparatively thin andlight flanged metallic plates with planking without loss of carryingcapacity, and the extended close contact of the plate and lining fromwhich the stiffness and strength of the composite structure arises willby reason of the modification of the braking and buffing shocks by thefriction-buffers of the end sill remain intact under the severe serviceincident to railway transportation, while repairs to either shell orlining can be circumscribed and readily made.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a composite car structure, the combination of flanged orcorrugated outer plates, and interior planking having kerfs or channelsfor the reception of the flanges or corrugations of the outer metallicplates, said outer plates and inner planking being in extended contact;substantially as and for the purposes specified.

2. In a car structure, a composite car-bottom comprised of flanged orcorrugated metal bottom plates and superposed planking having kerfs orchannels for the reception of the flanges or corrugations of themetallic bottom plates; substantially as and for the purposes specified.

3. A car structure consisting of composite floor and Walls, said floorand walls comprised of flanged or corrugated metallic plates, andplanking having kerfs or channels, said plates and planking being inextended contact; sub stantially as and for the purposes specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 4th day of October, 1902.
